TASI-IIRO MATSUI, OF WENATGHEE, WASHINGTON.

FOUNTAIN-PEN.

To all whom it-may concern:

Be it known that I, TASHIRO MATSUI, a citizen ofJapan, residing at Wenatchee, 1n

the county of. Chelan, State of Washington,

have invented certain new and useful Improvements 1n Fountain Pens; and I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art the pen.

Another object is to providea device of this character which is capable of being readily taken apart to be cleaned.

Other'objects and advantages-will be apparent from the following description when taken in connection with the accompanying drawing; in which:

Figure 1 is an elevationof the pen in closedposition, Fig. 2 is an elevation of the same in open position, Fig. 3 is a longitu-.

dinal sectional view through the pen in the position of Fig. 1, Fig. 4 is a longitudinal sectional view through the device in the position ofFig. 2, Fig. 5 is a fragmentary sec tion of the intermediate portion of the barrel showing the manner of separating the same when it is desired to fill the pen, Fig. 6 is a transverse section on the line 66 of Fig. 2, Fig. 7 is a longitudinal sectional view of the outer portion of the device showing the pen partially withdrawn within the barrel, and Fig. 8 is a transverse sectional view on the line 8-8 of Fig. 4:.

Referring particularly to the accompanying drawing, the barrel of the pen includes the three sections 10, 11 and 12, the sections 10 and 11 being interiorly threaded at their adjacent ends and engaged on an exteriorly threaded sleeve 13 which is formed with a longitudinal bore 14: therethrough.

Telescoped on to the other end of the section 11 is the beimc-mentioned section 12,

Specification of Letters Patent.

Application filed July 6, 1915. Serial No. 38,343.

the outer end of which has a thickened portion 15 formed with a threaded socket= 16 into which is screwed the threaded end of a rod 17 extending longitudinally through the sections 11 and 12 when the parts are in normal closed position. On the other end of the rod is ahead 18 provided with a threaded socket 19 into which is screwed the threaded stem 20 of a tapering glass pen nib 21. A spiral groove 22 is formed around the outer face of the pen nib, its inner end terminating at a point in line with the outer end of the groove 23 formed longitudinally on the peripheral face of the said head 18. The outer end of the section 10 is threaded to receive a cap 24, which cap is provided with a spring clip 25 for engagement with the pocket to hold the pen therein.

It will be noted that the sectionlO tapers at its outer end to permit the head 18 to fit snugly therein when in extended or operative position, and to prevent flow of ink except through the groove 23.

Assuming the parts of the pen to be in the position shown in section in Fig. 3, and it is desired to project the pen nib, the cap 24 is removed and the section 10 grasped in one hand while the section 12 is pushed longitudinally on the section 11 and toward the sectionlO. This movement offthe section 12 causes the longitudinal movement of the rod 17 and the movement of the pen nib outwardly beyond the end of the section 10.

As the head 18 moves outwardly the ink which is outwardly of and surrounding the pen nib and head will pass backwardly through the groove 23 to fill up the space behind the head. By tilting the pen into the position assumed when writing, ink will fiow from the space behind the head through the groove 23 and through the groove 22 of the pen nib to the point thereof. To close the pen the section 10 is again grasped in the hand as before, the section 12 is pulled in the opposite direction so as to draw the pen nib and head into the section 10. As the head moves into the section 10 the ink flows through the groove 23 and into the space outwardly ofv the head. The cap is then screwed on to the section 10 and the pen is ready to be put in the pocket.

It will be noted that the nib can be separated from the head, the rod 17 separated from the section 12 and that the sections 10 and 11 can be separated. When the parts are so separated access is had to the interiors of all of them so that either can be quickly and effectively cleaned.

WVhat is claimed is:

A fountain pen comprising a barrel section, a wall within the section and formed with a central opening, a rod slidable through the opening and carrying a head on the outer end thereof, said head being formed with a groove in one side, said head being adapted to snugly fit the outer end of the section, a conical pen nib secured in the head and formed with a spiral groove one end of which is disposed in alinement with one end of the said slot.

In testimony whereof, I aflix my signature, in the presence of two witnesses.
